A relay combined with a current output can be ordered as an option. The
relay either switches as a fault indicating relay in the event of a fault on the
pump and with "Liquid level low 1st stage" warning messages and "Liquid
level low 2nd stage" fault messages or is used as a pacing relay.
The behaviour is factory-programmed. If another switching function is
desired, the pump can be reprogrammed in the
The variable to be signalled for the current output can be selected in the
'ANALOG OUTPUT' menu.
The current output plus relay can be retrofitted and operates once it is
plugged into the board.
